Once developing a Spring application you might stumble across the problem ‘ No Session found for current thread’.
The obvious answer is that the service does not have the @Transactional annotation when using the dao. However this is a hard to forget step.
But this problem might occur when the controller tries to access the dataService.
How come since the custom UserDetailsService that you have implemented (which uses hibernate by the way) works fine?
The problem is that when you have more than one application context files (just like having a child context for the DispatcherServlet) the configuration should be applied since you are going to use hibernate.
